Embodiment one
Fig. 1 is a kind of localization method flow chart of RAM leakage that the embodiment of the present invention one is provided, and the method is applicable to
The internal memory revealed in the program debugging stage is to program carries out the situation of Quick finding and seeking, can be by the positioning of RAM leakage
System is performed.The system can be realized by way of hardware and/or software.The method specifically includes following steps：
Step 110, monitor application internal memory operation when, obtain for application and the identity information of storage allocation.
Generally, many standard library functions that can be directly invoked for having existed are had according to the programming language for being used,
Therefore the built-in function for realizing a certain concrete function can be directly invoked in software program, when in the absence of the built-in function for needing,
When needed, corresponding power function can be directly invoked with self-defined some power functions.
Can for example realize applying the function of internal memory by calling internal memory application function, in C language, to apply for one
Dram is needed comprising a header file i.e. " #include<malloc.h>" or " #include<stdlib.h>", then
The built-in function that application internal memory can just be directly invoked realizes the purpose of application internal memory, such as passes through code " void*malloc
(usigned size) " can obtain the internal memory of dynamically distributes, and the parameter of malloc functions is the memory size for needing application, can
To be configured；The return value of the function is the first address of the internal memory applied, the type of memory of return is void, can basis
Need to carry out return type conversion.To realize applying in C++ the function of internal memory then more it is simple some, it is necessary to comprising header file " #
include<iostream.h>", corresponding function need not be then so called when internal memory is applied for, as long as a keyword new
, such as " int*x；X=new int [] ", thus applies to a memory headroom for integer.When there is this in program
When a little specific keywords or internal memory application function, then it is assumed that monitored application internal memory operation, and then obtained for application
And the identity information of storage allocation.

Table, the nodal information that lookup matches with the identity information of the releasing memory, and the nodal information that will be found are followed from described
Deleted in loop chain table.
Specifically, similar with application internal memory, releasing memory can discharge function realization by directly invoking internal memory, for example,
If realized by calling " malloc " or " realloc " function during application internal memory, can be by adjusting during releasing memory
Realized with " free " built-in function；If during application internal memory being realized by keyword " new ", can pass through during releasing memory
" delete " sentence is realized.Certainly the function of other application/releasing memories is can also be, the present embodiment is not limited it
It is fixed.

Often apply for one section of internal memory, all the internal memory identity information of application is saved in default circular linked list, often discharge one
Section internal memory, all deletes the internal memory identity information matched with the internal memory being released preserved in circular linked list, represents in the section
Deposit and be released, in the absence of the situation of RAM leakage, therefore, in circular linked list it is remaining without deleted nodal information just
It is the identity information of RAM leakage, the internal memory of leakage can be navigated to according to the identity information, to realize to the fast of RAM leakage
Speed positioning.
